What it means
The word "certified" is used loosely in business conversation, so it pays to be precise about what is being asked for. In most cases it means audited statements signed off by a licensed public accountant, presented with a balance sheet, income statement, cash flow statement and notes.
Some parties instead use it to mean statements signed by a company officer, which is a far weaker assurance. An audit opinion comes in a small number of flavours and each carries a very different message.
An unqualified or clean opinion says the statements are fairly presented, a qualified opinion flags a specific exception, an adverse opinion says they are materially wrong, and a disclaimer says the auditor could not gather enough evidence to form a view. A bank reading a qualified opinion will want to understand exactly what was excluded.
The concept underpinning the whole exercise is materiality. Auditors do not check every transaction; they set a monetary threshold above which a misstatement would change the decisions of a reasonable user, then design testing to catch errors of that size.
This is why an audit can be clean even though small errors certainly exist somewhere in the accounts. Audit sits at the top of a ladder of assurance services.
A compilation simply presents management's numbers in the correct format with no assurance, a review applies limited procedures and gives negative assurance, and an audit involves testing evidence and gives positive assurance. Cost rises steeply along that ladder, so a business should buy the level its lenders and shareholders actually require.
Independence is what gives the opinion its value. The auditor must be free of financial interests and management responsibilities in the client, which is why the same firm generally cannot both prepare the underlying bookkeeping and audit it.
Losing that independence turns a certified statement into an expensive internal document.
In practice
Real-world examples.
Example
A construction company bidding for public sector work is told that tenders above a certain value must be supported by three years of certified financial statements. It commissions its first full audit specifically to become eligible to bid.
Example
A family manufacturer negotiating a $12,000,000 term loan agrees to a covenant requiring audited statements within 120 days of each year end. The audit cost is treated as a direct cost of the financing, not as an optional overhead.
Example
A software business preparing for an outside investment round is asked to upgrade from a review to a full audit. The investor's concern is revenue recognition on multi-year contracts, an area where limited review procedures would not provide enough comfort.
Formula
Calculation
Overall materiality is commonly set as a percentage of a chosen benchmark, most often 5% of profit before tax for a profitable trading company. Performance materiality is then set at roughly 75% of that figure, and the clearly trivial threshold at around 5% of it.
A distribution company reports profit before tax of $8,400,000. Overall materiality = $8,400,000 x 5% = $420,000, so a misstatement above that amount would be considered capable of changing a reader's decision.
Performance materiality = $420,000 x 75% = $315,000, the lower level used when designing individual tests so that several small errors do not add up past the overall threshold. The clearly trivial threshold = $420,000 x 5% = $21,000, below which identified errors are not even accumulated for discussion. If testing finds unadjusted errors totalling $180,000, that sits below the $420,000 overall threshold and the auditor can still issue a clean opinion.Case study
Seen in the real world.
Ardenhall Logistics is an illustrative, fictional freight business used to show how certified statements are used in practice. It had grown to about $46,000,000 of revenue on the strength of management accounts and a light-touch compilation prepared by a local accountant, which had always been enough for its overdraft.
When Ardenhall approached a larger bank for a $10,000,000 facility to buy a depot, the credit team declined to proceed without audited statements. The first audit surfaced two issues: accrued driver bonuses had never been recognised, and a portion of prepaid vehicle maintenance had been expensed in the wrong year. Adjusting both reduced reported profit before tax from $3,900,000 to $3,550,000.
In the illustrative outcome the bank still lent, but priced the facility on the adjusted profit figure. Ardenhall's finance director noted afterwards that the audit had cost roughly $95,000 and had lowered reported profit, yet it had also given the company access to a lower interest rate and a lender willing to fund growth, which no amount of internal reporting could have achieved.
Watch out
Common mistakes.
- Reading a clean audit opinion as a guarantee that the figures are exactly correct, when it only means no misstatement large enough to matter was found.
- Assuming an audit is designed to detect fraud, when its objective is a fair presentation opinion and only some fraud is material enough to be caught.
- Buying an audit when a lender would have accepted a review, and paying several times the fee for assurance nobody asked for.
Questions
People also ask.
What is the difference between audited and certified statements?
In everyday business use they usually mean the same thing, though "certified" is sometimes stretched to cover statements merely signed by a director, so it is worth asking which is meant.
Who can certify financial statements?
An independent accountant holding the relevant practising licence in the jurisdiction, who must have no financial interest in or management role at the company.
How long does an audit take for a mid-sized company?
Commonly six to twelve weeks from year end for a business of moderate complexity, with the first audit taking noticeably longer because opening balances also have to be verified.
